In the elderly. Hello livk --
diastolic pressure is commonly lower as we get older -- partly due to the increased stiffness of the vessel and low volume reserve.
However, please note that diastolic pressure is rarely accurate using the automated home BP machine -.

Older patients. As people age, the diastolic pressure usually decreases, so for an 80 year old, for example, the blood pressure will be 140/60. Nothing is done about it unless the person is having major symptoms of lightheadedness or passing out.

Depends. "too low" implies that it is a problem. 70 is lower than average but would not raise an eyebrow. 50-60 is unusual and would lead me to think, why? If you feel well it is probably not a problem. But if the diastolic pressure is on the low side, i would consider things that might cause that even if the patient is well. Leaking of the aortic valve for instance can cause a low diastolic pressure.

Diastolic BP. Normal range for diastolic blood pressure is 60 to 80 mmhg (mm of mercury). Diastolic BP less than 60 is low though most people will only start to feel symptoms at 50 or less.

60 mmHg. The normal diastolic pressure for adults is 80mmhg. Can be considered acceptable from 70 to 85 mmhg. Higher than that is prehypertension. Lowr than 70 mmhg is common normal finding in patients older than 70 years old. Diastolic blood pressure lower than 60 mmhg in adults younger than 65yo raises the ssupicion of valvular problems.

Less than 80 mmHg. A normal diastolic blood pressure is less than 80 mmhg. A diastolic blood pressure below 60 mmhg could be associated with symptoms such as lightheadedness.
For a person who is not taking any blood pressure medications and who has no symptoms, a low diastolic blood pressure is not thought to be dangerous.

Probably not. A low diastolic blood pressure with a normal diastolic blood pressure often is of no significance. In some people, their blood pressure sounds can be heard all the way down to 0 when nothing is wrong. A large difference between systolic and diastolic pressures (wide pulse pressure) may indicate aortic regurgitation, however. Check with your doctor.

Diastolic pressure. Low diastolic pressure relates to the peripheral vascular resistance, the intravascular volume and the integrity of the aortic valve. Any variable that changes one of these factors can relate to low diastolic pressure.
